Case Type   : 导入导出、备份恢复工具支持M*兼容性
Case Name   : gs_dump工具导出兼容M*建表同时创建索引语法
Create At   : 2023.05.04
Owner       : z@wan005
Description :
    1.创建兼容b库
    2.兼容b库下建表同时创建索引
    3.使用gs_dump工具导出表为纯文本格式
    4.导入之前导出的数据到新库
    5.连接导入库查询表
    6.清理环境
Expect      :
    1.成功
    2.成功
    3.成功
    4.成功
    5.成功，表结构和导出前一致，含索引
    6.成功
